Question

Accepted Answer

### Triangle A
# Explanation:
## Step1: Calculate the third angle
The sum of angles in a triangle is $180^\circ$. So the third angle is $180 - 30 - 25 = 125^\circ$.
## Step2: Classify the triangle
Since $125^\circ > 90^\circ$, the triangle is obtuse.
# Answer: Obtuse

### Triangle B
# Explanation:
## Step1: Identify the right angle
The triangle has a right angle (the square corner), so it's a right triangle.
# Answer: Right

### Triangle C
# Explanation:
## Step1: Identify the right angle
The triangle has a right angle (the square corner), so it's a right triangle.
# Answer: Right

### Triangle D
# Explanation:
## Step1: Calculate the third angle
The sum of angles in a triangle is $180^\circ$. So the third angle is $180 - 50 - 55 = 75^\circ$.
## Step2: Classify the triangle
All angles ($50^\circ$, $55^\circ$, $75^\circ$) are less than $90^\circ$, so the triangle is acute.
# Answer: Acute
